DAMPENING-MACHINE.

SPEGIFIQATIQN iornling 178.1% 032' LG'UfiSEIS Patent N0. 684,676, datedOCtG bGT 15, 1901.

Application filed February 14 1901. Serial model-l To an whom it mayconcerns Be itknown that I, FRANK B. Connvs, a enizen of the UnitedStates, residing at Sharon, in the county of Norfolk and State ofMassachusctt-s, have invented a certain new and usefulImprovementinDampening-lvlachines, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention has reference to improvements in devices for dampeningtextile, fibrous, or other fabrics.

The invention relates particularly to improvementsinthosepartsofdampeningmechanism whereby the dampening fluid is supplied.

One object of the invention is to so construct a nozzle fordampening-machines of this nature that the fluid passing therefrom injets may be more readily broken into a mist-like sprayas it strikes thedeflector.

Another object of the invention is to so construct a nozzle of thisnature whereby minute jets are delivered that the tendency of theorifices to clog will be overcome to a large extent.

Another object of the invention is to so construct a nozzle of thisnature that the same may be readily flushed from time to time.

Another object of the invention is to so con struct a nozzle for adampening-machine and mechanism codperating therewith that where aseries of such nozzles are mounted within a chamber they may be operatedfor flushing 5 from a mechanism outside the chamber.

The invention consists in a dampeningchamber having a deflector and in anozzle mounted therein. and having a series of inclined orifices wherebythe fluid is directed in converging jets meeting a common line ofimpingement at the deflector.

The invention also consists in the construction of the nozzle and in itscombination with the deflector.

5 The invention also consists in the means for flushing the valve andits seat.

The invention also consists in the valve having the exterior stem and inthe mechanism for moving the same.

The invention also consists in such other novel features of constructionand combination of parts as shall hereinafter be more fullydescribed,and pointed out in the claims.

Figure 1 represents a vertical sectional view of a dampencr-chamber ofthis nature with the improved nozzle and its valveoperating mechanismmounted therein, parts of the mechanism being broken away to moreclearly show the construction. Fig. 2 represents a similar view ofportions of the same, showing the operating mechanism in position fortie pressing the valve to increase the area of openingfor the flushingfiowage of fluid. Fig.

3 represents a view in elevation, at right angles with the positionsshown in Figs. 1 and 2, of the valve and its depressor-cam and thecam-shaft.

Similarnumbers of reference designate corresponding parts throughout.

In the manufacture of fabrics of a fibrous or textile nature it issometimes necessary to moisten the same or to maintain the same inmoistened condition between some of the steps of manufacture. Forthis-purpose, as well as for other more general moistening purposes, itis essential that the moistening fluid be supplied in a mist-likecondition in the nature of disintegrated spray, whereby the moisteningeffect of the fluid is most evenly distributed throughout the fabric. Toac- 8o complish this result, minute jets of water have heretofore beendirected against a deflector, the impingement against which causing thedistribution of the jets in drops of a size depending upon thecross-sectional area of the jets and the force with which they areimpelled against the deflector and somewhat upon the shape of thedeflector. Owing to the necessarily extremely small area of the jets theorifices of the nozzles, through which the water is directed toward thedeflector, soon become clogged by the impurities and foreign matter inthe water, thus causing annoyance and delay by the constant attentionrequired and the cleaning of the nozzles.

In carrying this invention into practice it has been found that thecommingling of several jets of water at the time of impingement on thedeflector more positively effects the disintegration of the jets intothe desired 10:) mist-like spray, this being particularly the case whenthe jets converge from separated directions to the point of impingement.It has also been found that the flushing of the orifices, through whichthe water is directed, can best be accomplished by a sudden increase inarea of the outlet to permit of the flowing or flushing therethrough ofa body of water.

In the drawings, 5 indicates a dampeningchamber, of any usualconstruction, having ends, as 6, the top '7, with its deflector 8, andthe drip pan or bottom 9. Through the bottom 9 is formed an opening,through which a connection 10 for anynumberof stand-pipes, as 10,extends, these pipes being connected with any water-supply and beingcontrolled by cocks, as 11, working through openings in the rear wall ofthe chamber. At the upper ends of the stand-pipes are axially-perforatedfittings, as 12, having ends, as 13, and shoulders, as 14, and screwedonto the end portions of these fittings are collars, as 15, the bore ofwhich is contracted toward its upper portion to form the truncatedconical valveseat 16. Movable in the valve-seat collars, as 15, arevalves, as 17, of a shape and size to closely fit the upper portion ofthe valveseat, as 16, and having in their peripheries the orifices orchannels 18 18, inclined laterally to the vertical axis of the valve.For the purposes herein to be set forth'this valve is furnished with theexterior valve-stem 19, having the curved shoulders 20, and the plate21, carrying the cross-pin 22.

In the ends, as U, of the dampener-chamber are secured the ends of thecam-shaft 23, on which at intervals corresponding to the location of thestand-pipes 10 are journaled collars, as 2%, having the curvedcam-fingers 25, which are engaged between the cross-pin 22 and theshoulders, as 20, of the valvestems, as 19, the plate 21 working betweenthese fingers,while from this collar 21 extends the cam-arm 26.

In suitable bearings in the ends, as 6, of the dam pen enchamber isjournaled the shaft '27, having at intervals corresponding to thedisposition of the arms 26 collars, as 28, fixed thereon by means ofset-screws, each of the collars having a radially-extending tripper 29,adapted when the shaft 27 is rotated to lift the free end of theassociated arm 26, when the shaft 27 is rotated, as by means of thehand-wheel 30. In practice the collars 28 are so arranged and secured onthe shaft 27 that the trippers, as 29, willsuccessivelyactuate theirassociated arms, as 26, to successively depress the valves of thenozzle.

With the valve 17 in the position shown in Fig. 1 the water pressingagainst the larger diameter of the valve will hold the valve against itsseat, the pressure forcing the water through the channels 18 18, wherebyit is directed in small jetsin the directions shown at A A, Fig. 1,which converge as they approach the deflector 8,and there being broughttogether from different angles are more com- I pletely dissipated in theform of spray.

When the channels become. clogged or at times to prevent c1ogging, thehand-wheel 30, is rotated slowly to successively bring the trippers, as29, into engagement with the relate'd arms, as 26, to lift the same anddepress the fingers 25 25, which, bearing on the rounded ends, as 20, ofthe valve-stems, as 19, force the valves downward against the pressureof the water, thus opening a large area to the flow of the water andeffecting the flushing out of all foreign matter that has become lodgedbeneath the valve or in the channels 18 18, this being materiallyassisted by the location of the channels in the periphery of the valves.

It is evident that other means than those herein shown may be utilizedto operate the valve and that the Valve-seat may be otherwise shaped orconstructed to hold the valve against the pressure of the water. So,also, channels similar to those marked 18 may be formed in the wall ofthe valve-seat instead of in the periphery of the Valve withoutdeparting from the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A dampening-machine comprising a deflector, and anozzle located opposite the defiector and having inclined outletswhereby converging jets of fluid may be directed toward the deflector.

2. A dampening-machine comprising an inclined deflector, and a nozzlelocated opposite the deflector and at a distance therefrom and having aseries of inclined outlets adapted to direct jets of fluid in convergingpaths toward the deflector, and means for flushing the outlets. I

3. Adampening-machinecomprisinganozzle having a valve-seat at its end, avalve movable in the seat and having an exterior stem, a depressormechanism in operative re lation with the valve-stem, and a rotatabletripper for the depressor mechanism.

4. A dampening-machine com prising a casing, a shaft rotatably mountedin the casing and furnished with a tripper extension, a depressorpivotally mounted and having an arm adapted to be engaged by the tripperand oppositely-extending fingers, a nozzle, and a valve in said nozzlehaving an exterior member operatively connected with said fingers,

5. The combination with the fitting 12, the collar15 secured thereto andhaving the valveseat 16, and the valve 17 movable in the seat and havingthe channels 18 18 and the valvestem 19 with the plate 21 and the pin22, of the collar23rotatably mountedin the machine and having thefingers 25 25, engaged with the plate 21, and the oppositely-extendingarm 26, the shaft 27 journaled in the machine the collar 28 fixedthereon and having the 1 tripper 29, and the hand-wheel 30 secured tosaid shaft 27.

In testimony whereof I affix my signature in presence of two witnesses.
